Accuracy

Each file is generated by code from the dimension table on its page, and every value in that table is cross-checked against at least two published catalogues. Threads are cosmetic and the models use nominal dimensions. The files are offered as they are: before manufacturing or approving a design, check the dimensions against the current edition of the standard and your supplier's data.
